939a1807fe glsl2: Initialize ir_function_signature::is_built_in. 
Fixes a valgrind error.

0cf545ec69 glsl2: Do ir_if_return on the way out, not the way in. 
The problem with doing it on the way in is that for a function with
multiple early returns, we'll move an outer block in, then restart the
pass, then move the two inside returns out, then never move outer
blocks in again because the remaining early returns are inside an else
block and they don't know that there's a return just after their
block.  By going inside-out, we get the early returns stacked up so
that they all move out with a series of
move_returns_after_block().

a62ef12ef2 glsl2: Make sure functions end with a return before doing ir_if_return. 
This catches a few remaining functions that weren't getting inlined,
generally operating on global or out variables and using an early
return to skip work when possible.

Fixes for i965:
glsl1-function with early return (3)

18964618a1 glsl2: Make ir_if_return handle if () { return } else { not return } 
This makes many remaining functions inlinable.

Fixes for i965:
glsl1-function with early return (1)
glsl1-function with early return (2)

806cb9f952 ir_to_mesa: Don't emit a duplicate return at the end of a function. 
It was harmless, but ugly.

0e19922558 glsl2: Allow use of _mesa_print_ir without a parse state on hand. 2010-07-29 15:09:31 -07:00

bf496862be glsl2: When dumping IR for debug, indent nested blocks. 
No more trying to match parens in my head when looking at the body of
a short function containing an if statement.

4285247f12 glsl2: Remove an inlined unvalued return statement. 
We already have asserts that it was the last call in the function, so
it's safe to remove after it got cloned in.

Fixes:
glsl-fs-functions-4.

35cc8b98ec glsl2/Makefile: Append to DEFINES rather than replacing them. 
Otherwise, we lose DEBUG, which causes mtypes.h to set NDEBUG, which
causes assertions to not happen, which is no fun for anyone.
